CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 390,602, dated October2,1888.

Application filed February 27, 1888. Serial No. 265,510. (No model.)

To aZZ whom it; may concern.-

Be it known that I, LEwIs E. HUNT, a citizen of the United States,residing at Hiram, in the county of Paulding and State of Georgia, haveinvented a new and useful Car-Coupling; and I do hereby declare thefollowing to be a full, clear, and exact description of the inven tion,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

This invention has more particular reference to the class ofcar-couplings in which the pin is raised from or lowered into its placewithout the necessity of going between the cars; and it consists ofmechanism for accomplishing this in a satisfactory manner and in theleast complicated way, all of which will be hereinafter fully described,and the parts claimed as new pointed out in the claims.

In the accompanying drawings,Figure l is a side elevation, partly insection, showing the pin in its place when coupled and other operativeparts. Fig. 2 is a front view of the draw-head, showing the pin-lifterand contigtr ous parts. Fig. 3 is a horizontal section of thedraw-head,'showing the shape of the recess for the pin.

In the figures, like reference-marks indicating corresponding parts inthe several views, A is the draw-head; B, the pin; Z), the linkguide,and b the spring attached at one end to the draw-head and at the otherto the pin in any suitable manner.

I do not confine myself to the form of spring shown, as it might beeither a flat spring attached to the pin in the same way substantiallyas the spring shown in Fig. 2, or one having a bifurcated end partiallyencircling the pin.

O is the eccentric arm for raising and forcing downwardly the pin, saidarm 0 being pivoted to the standard D, and having the levers d in thedesired number attached thereto.

The draw-head A may be of any form suitable for the purpose. The slopingunder face of the guide b is for the purpose of guiding the enteringlink under the end of the pin, and also prevents the pin beingaccidentally withdrawn from the draw-head. This guide will also causethe entering link to assist the arm in raising the pin on the entranceof the link in the opposing draw-head into the draw-head having no link.To keep the pin fromjarring out, the springb is attached in such amanner as to cause it to press the pin into the seat a in the bottom ofthe draw'head. In the upper end of the pin is a hole, through whichpasses the eccentric arm 0, which eccentric, when partially revolvedaround the pivot d in the standard I) in the direction of the arrow,Fig. 2, will, by its eccentricity, raise the pin to any height necessaryto allow of the free entrance of the link. The spring I) may bedispensed with, if desired, and the eccentricity of the arm 0 continuedto such an extent as to clamp the pin.

It will be seen in the drawings that for approximately one-fourth of itslength at the lower end the guide I) is sloped at a much more acuteangle to a horizontal line than for the residue of its length. This isfor the purpose of reducing the force required to cause the link to liftthe pin by reason of its contact I with this incline.

The bottom part, a, of the opening of the draw-head is flared orinclined for a considerable length, as shown, in order that the link maybe deflected byit and raised so as to prevent its passing under thestationary drawhead as it approaches thereto.

The operation of this device is as follows: To couple cars, the linkpassing into the drawhead is lifted in transit by the incline at thepoint a. A further entrance will force the pin up, owing to theinclination of the guide b, which inclination will also cause the linkto enter under the end of the pin as soon as said pin shall be raisedsufficiently to allow such entrance between the end of the pin and thebottom of the opening in the draw-head, on which entrance the spring I)and the force of gravity will cause the pin to return to its position,and the operation of coupling is complete. To uncouple the cars, the pinis raised by partially revolving the eccentric arm in the direction ofthe arrow, Fig. 2. The link may then' be freely withdrawn,and theoperation of uncoupling thereby completed.

This device may be attached to the drawhead of the ordinary pinand-linkcoupling without changing the form of the draw-head otherwise thanattaching the spring and standard in any desired manner and cutting arecess for the guide 1).

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In acar-coupling, the combination of the eccentric arm 0, thestandard D, and pin B, for the purpose specified.

2. In a car-coupling, the combination of the eccentric arm 0, thestandard D, the pin B, and the guide I), substantiallyas shown anddescribed, and for the purpose specified.

3. In a car-coupling, the combination of the eccentric arm 0, standardD, guide 1), spring b, and a lever or levers for operating the arm 0,substantially as shown and described, and for the purpose specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 2ith day of 20 February, 1888.

LEWIS E. HUNT.
